Power stage and power module design to minimize parasitic inductance for multilevel inverter and converter

A vehicle, comprising:

• an inverter having a power module, the power module including:
• a high side bus including a first switch, wherein a high side current is configured to flow through the first switch in a first direction;
• a low side bus including a second switch, the low side bus parallel to the high side bus, wherein a low side current is configured to flow through the second switch in the first direction;
• and
• an AC output bus parallel to the high side bus and the low side bus, wherein an output current flows through the AC output bus in a second direction opposite to the first direction,
• wherein the power module comprises a first plane of switches, a second plane of switches and a third plane of switches, each parallel to each other, wherein the AC output bus includes a first AC output bus disposed between the first plane of switches and the second plane of switches and a second AC output bus disposed between the second plane of switches and the third plane of switches.
